import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a = scanner.nextInt();
        int b = scanner.nextInt();
        scanner.close();
        System.out.print((a+b)+" ");
       if(a>b){
        System.out.print((a-b)+" ");
        System.out.print((a*b)+" ");
        System.out.print((a/b)+" ");
        System.out.print(a%b);
       }else{
        System.out.print((b-a)+" ");
        System.out.print((a*b)+" ");
        System.out.print((b/a)+" ");
        System.out.print(b%a);
       }

    }
}

直接在输出结果后加“ ”就好
